basic information
Evolution of Semiconductor Technology and RF Power Control Solid-state power source modules integrate amplification circuits, power combiners, filters, sensors, digital controls, protection circuits, and cooling mechanisms. The product forms are categorized into compact power modules, integrated generators, and modular subsystems that connect multiple units in parallel. Key evaluation metrics include frequency, output power, conversion efficiency, output stability, resistance to reflected power, pulse control, and cooling methods. In semiconductor materials, mature LDMOS is widely adopted for high-frequency and high-power applications, while GaN, particularly GaN-on-SiC, is gaining prominence in the microwave domain where high output density and thermal stability are required. In recent years, in addition to improving output, control functions tailored to process conditions, such as fast frequency switching, multi-level pulse control, reflected power management, and remote diagnostics, have become the focus of product differentiation.
